MySQL 服务器拒绝卸载

  • 772

所以，我输入“apt install mysql-server-8.0”，它返回：

Building dependency tree

The following packages will be upgraded:

我试过卸载，重新安装，安装。没有任何效果。我将相关.deb文件移至/tmpfrom /var/cache/apt/archives/，但仍然无法将其从我的系统中取出。mysql 5.7 似乎仍在这台机器上，尝试删除它会导致相同的错误。我已经束手无策了。谷歌没有帮助（遵循了许多方向，包括这里的一个：https : //itsfoss.com/dpkg-returned-an-error-code-1/ 无济于事）。

所以我做了：dpkg --configure -a 它吐了回来：

dpkg: dependency problems prevent configuration of mysql-server-8.0:
 mysql-server-8.0 depends on mysql-server-core-8.0 (= 8.0.20-0ubuntu0.20.04.1); however:
  Version of mysql-server-core-8.0 on system is 8.0.21-0ubuntu0.20.04.3.

    我想我解决了这个问题（经过很多小时搜索谷歌）：

    $sudo nano /var/lib/dpkg/info/mysql-server-core-8.0.prerm

    注释掉命令if周围的语句invoke.d（或其他任何语句），保存并退出 nano。

    $sudo apt remove mysql-server-core-8.0

    1. 安装synaptic：“图形前端到 apt，Ubuntu 中的包管理系统”
    $ sudo apt-get install synaptic
    1. Mark All Upgrades从选项卡中单击。

    该问题可能是由某些依赖项引起的，这些依赖项未预先安装在您的机器中。
